Arsenal fans react on Twitter to Yaya Sanogo and Emi Martinez's displays

A look at how Arsenal fans reacted to Yaya Sanogo and Emi Martinez's displays against Borussia Dortmund.

Two surprise Arsenal stars featured in the win over Borussia Dortmund, and both played as if they had done so for the Gunners for years.

Yaya Sanogo appeared a much more improved version of his previous self - scoring his first goal since joining the club. All who mocked his inclusion, with the absence of Olivier Giroud and Danny Welbeck, were quickly having to retract their comments after he netted just 73 seconds in.

He had two shots on goal in total, scoring with the only one which hit the target. Sanogo created one chance, winning three aerial duels, and winning one tackle.

Perhaps the only disappointing area of his play was his 59 per cent pass completion rate, but this was more down to the opposition, with Alex Sanchez's even lower at 55 per cent.

Another who really impressed was goalkeeper Emi Martinez. The Argentine featured against Anderlecht two group games ago, and continues to look good.

He was in thanks to an injury to Wojciech Szczesny, while David Ospina is also nursing long-term fitness issues which Arsene Wenger has previously discussed prevents him playing twice within a week at present.

It was the first clean sheet Martinez has kept for the first team, pulling off an excellent save late on to deny the Bundesliga side a lifeline.

Calls for him to replace Wojciech Szczesny may be premature, but he has managed to show that if and when he is called upon again he can be relied upon, which will give the defenders reason to be confident.

Here's a look at how fans reacted to performances of both players on Twitter...
